Black double-sheath Rubber welding cable. Rated 600V, extremely fine-stranded tinned copper Class 6, 10–95mm². For standard colour for negative/return leads in welding circuits.
Black colour-coding on welding cables serves a critical function in multi-operator workshops and site welding operations: standard colour for negative/return leads in welding circuits. Colour-coded welding leads reduce the risk of incorrect polarity connection, speed up setup time, and satisfy site safety requirements for cable identification in environments where multiple welding sets operate simultaneously.
The double rubber sheath construction provides a primary insulating layer and a tough outer protective sheath — giving the cable excellent resistance to the mechanical abuse of workshop and site welding environments: grinding sparks, weld spatter, dragging on concrete, and contact with oils and chemicals.

DC welding requires correct polarity for electrode-positive (DCEP) or electrode-negative (DCEN) processes. Colour-coded leads make polarity identification instant — eliminating the risk of reversed polarity that causes poor penetration, porosity, and spatter.
In workshops with multiple welding bays sharing a common earth bus, colour coding identifies which lead belongs to which welding set — preventing accidental cross-connection of return currents that can cause stray current damage to workpieces and fixtures.
A single-sheath welding cable that gets cut through the outer sheath exposes bare conductor immediately. The double-sheath construction provides a second layer of protection — the primary insulation remains intact even when the outer sheath is abraded through, maintaining electrical safety until the cable is inspected and replaced.
